bone mineral density

Purpose: Osteoporosis is a decrease in bone density among older adults that can cause painful fractures and disability. One of the most important effective non-pharmacological interventions is having appropriate and continuous physical activity.  The aim of this study was to investigate the relationship between serum calcium and alkaline phosphatase with femur bone mineral density in active and inactive men. Method: This study was semi-experimental. 35 active and 35 inactive elderly men aged 65 to 80 years with medical records were selected. Anthropometric characteristics, serum calcium and alkaline phosphatase of subjects were used as effective indicators of osteoporosis. Pearson's correlation coefficient was used to find the relationship between femur mineral density and serum calcium and alkaline phosphatase, data analysis was done using SPSS version 26 Software. Results: The results of this research showed that in both groups of active and inactive men, there was a significant relationship between serum calcium and alkaline phosphatase and femur mineral density (P≤0.05). No significant relationship was found between the height index and mineral density of the femur (P≥0.05). Conclusions: In general, the results show that there is a significant relationship between bone density and weight, age, calcium, phosphorus, and serum alkaline phosphatase of all subjects, and the effect of exercise on other bone density indicators can be investigated.

Purpose: Osteoporosis usually starts at a young age and progresses slowly over time. Therefore timely diagnosis of this disease plays an effective role in raising the level of health and public health in the society. The aim of this study was to investigate the relationship between some indicators of osteoporosis and bone mineral density of the pelvis in active elderly men. Methods: This study was semi-experimental. 25 active elderly men with the age range of 60 to 85 years were selected as available and with medical records. Anthropometric characteristics and serum indices of subjects were used as effective indices of osteoporosis. Pearson's correlation coefficient was used to find the relationship between bone mineral density of the pelvis and effector indices, data analysis was done using SPSS version 26 software. Results: The results of this research showed that in the active elderly men, there is a significant relationship between age (P=0.044), body mass index (BMI) (P=0.021), serum calcium (P=0.037) and phosphorus levels (P=0.046) and alkaline phosphatase (P=0.016), with bone mineral density (BMD) of the pelvis. No significant relationship was found between vitamin D with BMD of the pelvis (P=0.055). Conclusion: In general, the results show that there is a significant relationship between bone density and body mass index, calcium and serum alkaline phosphatase indices in active elderly men. Therefore, it is possible to use the serum levels of these indicators in predicting this disease, and exercise may also be one of the influencing factors, so the effect of exercise on other bone density indicators can be investigated.
